Question 1

What is the Tamron 100-400mm f/4.5-6.3 Di VC USD (Model A035) good for?

Accepted Answer

The 100–400mm range makes it ideal for wildlife, birding, sports, and travel photography where you need flexible reach without carrying multiple lenses. The 1.5m minimum focus distance adds close-range versatility — useful for insects or small animals — and the built-in VC helps keep shots sharp when shooting handheld in lower light or at slower shutter speeds.

Question 2

Is the Tamron 100-400mm compatible with all Canon EF cameras?

Accepted Answer

Yes — it uses the Canon EF mount, so it works on both full-frame and APS-C Canon DSLRs. On an APS-C body the focal length multiplies by roughly 1.6x, giving you an effective range of around 160–640mm, which is especially useful for birding and distant wildlife.

Question 3

How does the Tamron 100-400mm compare to the Canon 100-400mm lens?

Accepted Answer

The Tamron 100-400mm f/4.5-6.3 Di VC USD (A035) is generally lighter and available at a significantly lower price point, making it an attractive alternative for Canon EF shooters. The Canon EF 100-400mm L series has a wider maximum aperture at the long end and Canon's USM autofocus system, but many photographers find the Tamron's image quality and VC performance competitive for the price. For most wildlife and sports use, the Tamron holds its own — especially on used budgets.

Question 4

How does the Tamron 100-400mm compare to the Sigma 100-400mm?

Accepted Answer

Both cover the same focal range and are third-party alternatives to first-party super-telephotos. The Tamron A035 weighs 1135g and uses a 67mm filter thread, while the Sigma 100-400mm Contemporary is slightly heavier with a 67mm thread as well. Image quality is closely matched between the two, so the choice often comes down to autofocus feel and price — both are worth testing if you can find used copies to compare.

Question 5

Does the Tamron 100-400mm have image stabilisation?

Accepted Answer

Yes — it includes Tamron's VC (Vibration Compensation) system. This is particularly useful at 400mm where camera shake is most visible, and helps you shoot at lower shutter speeds handheld. It's a meaningful advantage over lenses without stabilisation, especially on bodies that don't have in-body image stabilisation.

Question 6

What filter size does the Tamron 100-400mm use?

Accepted Answer

The filter thread is 67mm — a common diameter shared by many standard telephoto and mid-range zoom lenses, so there's a good chance you already have compatible filters in your kit. This makes adding a UV filter for protection or a circular polariser relatively affordable.

Question 7

Is the Tamron 100-400mm f4.5-6.3 sharp at 400mm?

Accepted Answer

Centre sharpness at 400mm is generally well-regarded for a zoom in this class. Corner sharpness at maximum focal length can be softer wide open — a commonly noted characteristic in user reviews — but stopping down slightly improves this noticeably. For wildlife and sports, where subjects tend to be in the centre of the frame, this is rarely a practical issue.

Question 8

What is the minimum focus distance of the Tamron 100-400mm?

Accepted Answer

The minimum focus distance is 1.5 metres across the zoom range. This means you can get relatively close to smaller subjects like insects or reptiles while using the wide end of the zoom — something that larger telephoto primes can't always match.

Question 9

Is buying a used Tamron 100-400mm Di VC USD worth it?

Accepted Answer

Absolutely — this is one of the lenses where the used market makes strong sense. It's a robust, weather-resistant build that holds up well over time, and optical quality doesn't degrade with age on a well-maintained copy. Every used lens at Camera-tweedehands.nl comes with a minimum of 12 months warranty and has been professionally inspected, so you're not taking a risk on unknown condition.

Question 10

Can I use the Tamron 100-400mm Canon EF on a mirrorless Canon camera?

Accepted Answer

With a Canon EF-to-RF mount adapter, you can use this lens on Canon RF mirrorless bodies. Autofocus and image stabilisation generally continue to function through the adapter, though performance may not be identical to a native RF lens. For anyone already using Canon EF glass, this is a practical way to extend the lens's life on a newer body.

Question 11

How heavy is the Tamron 100-400mm f/4.5-6.3 Di VC USD?

Accepted Answer

It weighs 1135g — notably lighter than many first-party 100–400mm lenses and most telephoto primes in the same reach category. For a full day shooting wildlife or sports in the field, that weight saving is real and appreciated, especially if you're also carrying a body and other gear.

Question 12

What aperture blades does the Tamron 100-400mm have, and does it affect bokeh?

Accepted Answer

The lens has 9 rounded aperture blades. More blades generally produce smoother, more circular bokeh in out-of-focus areas, which matters when isolating wildlife subjects against blurred backgrounds. At 400mm and f/6.3, background separation can still be pleasing, particularly with some distance between subject and background.
